Can you sit on any seat on the train?

No. There are 2 reserved mum-to-be seats on each train. These are seats C01 and C02 in Coach C, which are reserved for vulnerable customers which includes the elderly, disabled and now pregnant women who have a 'mums-to-be' pass.

What if C01 and C02 are taken by an elderly or disabled person?

You'll need to find the train manager or other on-board staff who will then help you find a seat in standard class, or First Class if none is available. As long as you have your mum-to-be pass.

Oh wait, there's a bit more...

As part of a mum-friendly initiative, Virgin Trains will be keeping a stock of 'emergency essentials' on board such as nappies, baby food and sterilised bottles for mums with babies in urgent need. While these items will be free of charge for those who need them, they're not free gifts for mum-to-be passholders.

And if you're travelling first class on the Virgin Manchester to Euston train...

You may get a chance to sample Virgin Trains' new Cravings Collection. It’s a range of snacks inspired by a poll into pregnancy cravings. The research found these were the top cravings:

chocolate (34%)

crisps (21%)

sweets (16%)

Among the more unusual top 20 cravings were chillies, chorizo, marmite and anchovies and 4% of pregnant women craved charcoal.

So what has Virgin Trains done? It's offering pregnant passengers a selection of treats including chorizo jam, chilli sauce, charcoal crisps and even a jar of anchovies.
